git-commit: partial commit of paths only removed from the index
Because a partial commit is meant to be a way to ignore what are

just record what is in A on the filesystem. The previous patch
made the command sequence to barf, saying that A has not been

Split grep arguments in a way that does not requires to add /dev/null.
In order to (almost) always show the name of the file without
relying on "-H" option of GNU grep, we used to add /dev/null to
the argument list unless we are doing -l or -L. This caused
"/dev/null:0" to show up when -c is given in the output.
It is not enough to add -c to the set of options we do not pass
/dev/null for. When we have too many files, we invoke grep
multiple times and we need to avoid giving a widow filename to
the last invocation -- otherwise we will not see the name.
This keeps two filenames when the argv[] buffer is about to
overflow and we have not finished iterating over the index, so
that the last round will always have at least two paths to work
with (and not require /dev/null).
An obvious and the only exception is when there is only 1 file
that is given to the underlying grep, and in that case we avoid
passing /dev/null and let the external "grep -c" report only the
number of matches.
Documentation/git-config.txt: AsciiDoc tweak to avoid leading dot
Bram Schoenmakers noticed that git-config document was formatted
incorrectly. Depending on the version of AsciiDoc and docbook
toolchain, it is sometimes taken as a numbered example by AsciiDoc,
some other times passed intact to roff format to confuse "man".
Since we refer to the repository metadata directory as $GIT_DIR
elsewhere, work it around by using that symbolic name.
Documentation/git-archive.txt: a couple of clarifications.
The description of the option gave impression that there
were several formats available by using three dots. There are
no other formats than tar and gzip currently supported.
Clarify that the archive goes to the standard output.

This adds more proper rename detection limits. Instead of just checking
the limit against the number of potential rename destinations, we verify
that the rename matrix (which is what really matters) doesn't grow
ridiculously large, and we also make sure that we don't overflow when
doing the matrix size calculation.
This also changes the default limits from unlimited, to a rename matrix
that is limited to 100 entries on a side. You can raise it with the config
entry, or by using the "-l<n>" command line flag, but at least the default
is now a sane number that avoids spending lots of time (and memory) in
situations that likely don't merit it.
The choice of default value is of course very debatable. Limiting the
rename matrix to a 100x100 size will mean that even if you have just one
obvious rename, but you also create (or delete) 10,000 files, the rename
matrix will be so big that we disable the heuristics. Sounds reasonable to
me, but let's see if people hit this (and, perhaps more importantly,
actually *care*) in real life.

When making a partial commit, git-commit uses git-ls-files with
the --error-unmatch option to expand and sanity check the user
supplied path patterns. When any path pattern does not match
with the paths known to the index, it errors out, in order to
catch a common mistake to say "git commit Makefiel cache.h"
and end up with a commit that touches only cache.h (notice the
misspelled "Makefile"). This detection however does not work
well when the path has already been removed from the index.
If you drop a path from the index and try to commit that
partially, i.e.
the command complains because git does not know anything about
COPYING anymore.
This introduces a new option --with-tree to git-ls-files and
uses it in git-commit when we build a temporary index to
write a tree object for the partial commit.
When --with-tree=<tree-ish> option is specified, names from the
given tree are added to the set of names the index knows about,
so we can treat COPYING file in the example as known.
Of course, there is no reason to use "git rm" and git-aware
people have long time done:

On filesystems where it is appropriate to set core.filemode

git-commit does not notice a file (execute) permission change.
A fix requires noting the new file execute permission in the

Make --no-thin the default in git-push to save server resources
1) pushes happen less often than fetches, so the bandwidth saving is
much less visible in that case overall.
2) thin packs have to be complemented with missing delta bases to be
valid, so many received thin packs will take more disk space.
3) the bother of repacking should be distributed amongst "clients"
i.e. fetchers and pushers as much as possible, and not the server
being fetched or pushed, to keep disk and CPU usage low on the
server.
This is why a fetch should get thin packs but a push should not.
Both Nico and I have been assuming that --no-thin was the default
behavior of git-push ever since Nico introduced --fix-thin into the
index-pack process, which allowed fetch and receive-pack to avoid
exploding packfiles received during transfer. This patch finally
makes it so.

Most of this patch code and message was written by Shawn O. Pearce.
I made some tests to know what the problem was, and then I changed
the code related with the SIGPIPE signal.
If the user has misconfigured `user.signingkey` in their .git/config
or just doesn't have any secret keys on their keyring and they ask
for a signed tag with `git tag -s` we better make sure the resulting
tag was actually signed by gpg.
Prior versions of builtin git-tag allowed this failure to slip
by without error as they were not checking the return value of
the finish_command() so they did not notice when gpg exited with
an error exit status. They also did not fail if gpg produced an
empty output or if read_in_full received an error from the read
system call while trying to read the pipe back from gpg.
Finally, we did not actually honor any return value from the do_sign
function as it returns ssize_t but was being stored into an unsigned
long. This caused the compiler to optimize out the die condition,
allowing git-tag to continue along and create the tag object.
However, when gpg gets a wrong username, it exits before any read was done
and then the writing process receives SIGPIPE and program is terminated.
By ignoring this signal, anyway, the function write_or_die gets EPIPE from
write_in_full and exits returning 0 to the system without a message.
Here we better call to write_in_full directly so we can fail
printing a message and return safely to the caller.
With these issues fixed `git-tag -s` will now fail to create the
tag and will report a non-zero exit status to its caller, thereby
allowing automated helper scripts to detect (and recover from)
failure if gpg is not working properly.

In normal use cases, the performance wins are not overly impressive:
we get something like 5-10% due to the slightly better locality of
memory accesses using the packed structure.
However, since the data structure for index entries saves 33% of
memory on 32-bit platforms and 40% on 64-bit platforms, the behavior
when memory gets limited should be nicer.
This is a rather well-contained change. One obvious improvement would
be sorting the elements in one bucket according to their hash, then
using binary probing to find the elements with the right hash value.
As it stands, the output should be strictly the same as previously
unless one uses the option for limiting the amount of used memory, in
which case the created packs might be better.

Don't allow contrib/workdir/git-new-workdir to trash existing dirs
Recently I found that doing a sequence like the following:
git-new-workdir a b
...
git-new-workdir a b
by accident will cause a (and now also b) to have an infinite cycle
in its refs directory. This is caused by git-new-workdir trying
to create the "refs" symlink over again, only during the second
time it is being created within a's refs directory and is now also
pointing back at a's refs.
This causes confusion in git as suddenly branches are named things
like "refs/refs/refs/refs/refs/refs/refs/heads/foo" instead of the
more commonly accepted "refs/heads/foo". Plenty of commands start
to see ambiguous ref names and others just take ages to compute.

HPA noticed that yum does not like the newer git RPM set; it turns out
that we do not ship git-p4 anymore but existing installations do not
realize the package is gone if we do not tell anything about it.
David Kastrup suggests using Obsoletes in the spec file of the new
RPM to replace the old package, so here is a try.
This is based on Martin Koegler's idea to keep the object that
was successfully used as the base of the delta when it is about
to fall off the edge of the window. Instead of doing so only
for the objects at the edge of the window, this makes the window
a lru eviction mechanism. If an entry is used as a base, it is
moved to the last of the queue to be evicted.
This is a quick-and-dirty implementation, as it keeps the original
implementation of the data structure used for the window. This
originally was done as an array, not as an array of pointers,
because it was meant to be used as a cyclic FIFO buffer and a
plain array avoids an extra pointer indirection, while its FIFOness
eant that we are not "moving" the entries like this patch does.
The runtime from three versions were comparable. It seems to
make the resulting chain even shorter, which can only be good.
git-diff: resurrect the traditional empty "diff --git" behaviour
The warning message to suggest "Consider running git-status" from
"git-diff" that we experimented with during the 1.5.3 cycle turns
out to be a bad idea. It robbed cache-dirty information from people
who valued it, while still asking users to run "update-index --refresh".
It was hoped that the new behaviour would at least have some educational
value, but not showing the cache-dirty paths like before meant that the
user would not even know easily which paths were cache-dirty, and it
made the need to refresh the index look like even more unnecessary chore.
This commit reinstates the traditional behaviour, but with a twist.
By default, the empty "diff --git" output is totally squelched out
from "git diff" output. At the end of the command, it automatically
runs "update-index --refresh" as needed, without even bothering the
user. In other words, people who do not care about the cache-dirtyness
do not even have to see the warning.
The traditional behaviour to see the stat-dirty output and to bypassing
the overhead of content comparison can be specified by setting the
configuration variable diff.autorefreshindex to false.
git-tag: Fix -l option to use better shell style globs.
This patch removes certain behaviour of "git tag -l foo", currently
listing every tag name having "foo" as a substring. The same
thing now could be achieved doing "git tag -l '*foo*'".
This feature was added recently when git-tag.sh got the -n option
for showing tag annotations, because that commit also replaced the
old "grep pattern" behaviour with a more preferable "shell pattern"
behaviour (although slightly modified as you can see).
Thus, the following builtin-tag.c implemented it in order to
ensure that tests were passing unchanged with both programs.
Since common "shell patterns" match names with a given substring
_only_ when * is inserted before and after (as in "*substring*"), and
the "plain" behaviour cannot be achieved easily with the current
implementation, this is mostly the right thing to do, in order to
make it more flexible and consistent.
Tests for "git tag" were also changed to reflect this.

git-svn: fix dcommit clobbering upstream when committing multiple changes
Although dcommit could detect if the first commit in the series
would conflict with the HEAD revision in SVN, it could not
detect conflicts in further commits it made.
Now we rebase each uncommitted change after each revision is
committed to SVN to ensure that we are up-to-date. git-rebase
will bail out on conflict errors if our next change cannot be
applied and committed to SVN cleanly, preventing accidental
clobbering of changes on the SVN-side.
--no-rebase users will have trouble with this, and are thus
warned if they are committing more than one commit. Fixing this
for (hopefully uncommon) --no-rebase users would be more complex
and will probably happen at a later date.
Thanks to David Watson for finding this and the original test.
If the configuration of the user has "diff.color = true", the
output from "log" we invoke internally added color codes, which
broke the parser.
